x+y+z=100

i need software. there 6 buttons 3 leds 3 3x7 segment displays. buttons x, y , z, x1, y1, z1. x button up, x1 button down, y button up, y1 button down, z button up, z1 down button. x, y, z buttons have 3x7 segment displays. here want see leds connected output, sensitive pwm connected buttons, , pwm values in 3x7 segment displays. operating logic of circuit, example, every time press or hold down x button, pwm signals seen 1 step , rising values seen numbers in 3x7 segment x indicator. x output led appear running in percent pwm. example when hold down x button or press individually, write 70 in 3x7 x segment. value indicates pwm 70%. x led 70% working. add 30% value y , z buttons. can not 70% of x value. x value can take value number down. need x1 button it. press x1 button 20 times; x value reduced 20%. x value, 3x7, x marks number 50 in notation. y , z values not change. y , z same. y = 15, z = 15 numbers same in 3x7 y , z segments. increase y , z values; y , z buttons used. highest total value of y , z 50%. logic short.

this post made head spin.
maybe wise start 7-segment display , 2 buttons. 1 up, , 1 down.
plenty of 7-segment sketches if google that, explained in other post.
